[提要]  軟土地基的沉降受眾多因素的影響，在時(shí)序上常表現(xiàn)出復(fù)雜的非線性和不確定性。對(duì)于軟土地基的非線性沉降，獲得的數(shù)據(jù)有限。因而，已有的成功經(jīng)驗(yàn)在軟土地基沉降預(yù)測(cè)中的運(yùn)用具有重要意義。結(jié)合工程實(shí)例對(duì)各種軟土地基沉降預(yù)測(cè)方法進(jìn)行探討。

The settlement of a soft soil ground often manifests as a complicated nonlinear feature at time sequence due to the influence of many factors. It is characterized by limited data, instability, etc. thus, use of the existing experience and knowledge is verylmportant in settlement analysis of a soft soil ground. The prediction method for the settlement of a soft soil ground with the engineering practice is proposed.
